Pliocene/Miocene Invertebrates, Humboldt County CA.
Spoons posted a topic in Member-to-Member Fossil Trades
Hey everyone! This will be my first attempt at a trade in the TFF. Im offering a variety of fossils from the Price Creek Formation of Humboldt County, Northern California. This formation has been dated to late Miocene early Pliocene. As far as to what I’m looking for in this trade, I love all things Mollusca! Gastropods, Bivalves, Ammonites, Belemnites or Brachiopods, I’ll take them all. Invertebrates of any kind will strike my fancy though. The weirder the better. I’ve seen some Ram’s Horn Oysters that are awesome! I have no qualms about trading for these as a whole set, however shipping would be cheaper. I’m willing to ship anywhere in the United States, if your international I’m afraid that you’ll have to absorb that cost. I really appreciate all the knowledge that members have been forthcoming with sharing. Please pm me if your interested. -Nick -
Hello all Up for trade is this Chilean Carcharodon carcharias. It was found in the Huarra formation, near Antofagasta. The tooth is just over 2 inch measured on the longest side. I want to trade this for trilobites, dinosaur, Crocodile or other reptile stuff, Kem Kem material, insects, fossil fish or something surprising. Unfortunately, I will not be able to send this piece untill the quarantine in my country is lifted.

Last one from the Peace River! There’s three ridges where my finger is pointing.
-
Another stumper! This one has a sheen to it that doesn’t show up well in the photos. I try to show all sides. It’s cubed in shape.

First time poster! Going through my collection and I have some that stump me. Any idea on this one?

from Peace river, Florida. Thoughts!

Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to commonly observe the item of interest; paler orange indicates times in earth history to less commonly observe the item of interest. White indicates very little to no practical probability of observing the item of interest. Please keep in mind that the listed indicators are things like “conspicuous horn corals,” purposefully declining to address rare encounters with groups of low preservation potential, low recognizability, etc. Got additions/amendments, especially for the groups mentioned above? Toss them in the comments below! Thank you..... https://docs.google.com/spreadsheets/d/1tVm_u6v573V4NACrdebb_1OsBEAz60dS1m4pCTckgyA- 5 replies

Thoughts on age/epoch? Ancient or not? Found on a gravel bar on a river in Southern Minnesota.

Recently found this fossil in Capitola Beach, California. I found an abundance of fossilized shells in the area, but this one looked dissimilar. Anyways, is it possible that this is just a disfigured shell? Or is it something else? Thanks for your time!

Recently stumbled across this, possible, fossil in Capitola Beach, CA. I found an assortment of fossilized shells but was unsure of this find. Anyways, I’m new to fossil hunting and don’t have an exceeding amount of experience, so any knowledge regarding what this could possibly be would be helpful. Thanks!

Hi, just going through some rocks I brought back from Norfolk, UK, thinking quite a few may be fossils (I didn't have long so just grabbed anything I thought looked suspiciously organic by intuition) and as it turns out I think I was quite correct in a number of cases - I think I have quite a few pieces of whale and and a few little bits of mammoth tooth. Trying to confirm this to myself led to a lot of reading and learning online about the local geological formations involved and also whale anatomy, both new topics for me which I always enjoy delving into - part of the enjoyment of fossil hunting for me - I'm less of someone looking for beautiful specimens for display (though I'm not going to turn those down!) and more someone who loves the detective work of trying to identify obscure parts and recreate some aspect of the vanished world before us from its traces. And searching through whale anatomy and what these weird chunks could be I came across a picture of a whale periotic and realised that the weird little pot structure I had was almost definitely one of these, which if I am correct is good because I believe they are one part of a fragmented whale anatomy that is quite diagnostic. Also I then realised that a strangely hooked piece I found right next to it could well be the tympanic! The preservation here is unusual because many theorise that these kind of whale fossils were first laid down in sandstone in the Miocene when Norfolk was covered with a shallow warm sea, and then later in the Pliocene and early Pleistocene when temperatures dropped sea levels dropped too and the area became land (part of the reason the geology of this area is interesting is the constant transgression and regression of the sea over a few million years), these Miocene rocks were eroded away and the harder fossils reworked into new estuarine or nearshore sediments of this era, often but not always with a layer of hard iron-rich concretion coating them which helped protect them (I guess one question would be, is there anyway of easily removing this hard concretion layer?) So if I am right, these are bones from Miocene whales (many showing signs of shark damage), reburied in the Pliocene / Early Pleistocene and then finally eroded out again in the modern day - quite a journey! Anyway, enough background, for starters I'd love to see what people think about this periotic / tympanic. Am I right? Here's a summary of my findings (note I used a pic of dolphin periotic someone posted here for comparison so I hope that isn't too cheeky)

Hello gang. I have a fossil walnut described as: Cynorrea junglans, Pliocene, from Cuyck, Holland. Can someone please tell me it I have it identified correctly? Thanks in advance.

Good evening everyone, long time I don't show up here (my bad, my thesis is ...well...a thesis). Almost 2 weeks ago I had the pleasure to visit with a friend the "Museo Civico di Scienze Naturali Malmerendi" located in Faenza. Even if it's not the biggest nor the most famous natural history museum of Emilia Romagna I consider it one of the best I've seen so far in Italy. Most of the speciments (Pliocene / Pleistocene) were collected in the area near the city. Mammals are well represented, maybe the most peculiar is what I think is the holotype of the only aardvark specie from our country (if I'm wrong please tell me). Several fishes (in particular a large grouper in matrix) and mollusks are also displayed.

I posted a short trip report, and included this vertebra which i can't id. It is almost perfect. I put it to a flame test because I thought perhaps it was recent, but no smell whatsoever. It is about 1"wide from wing to wing, and also about the same from the bottom to the tip of the top flange. I fell in love with it as I pulled it out of the chalky white clay from the bottom of the stream where I was screening for shark's teeth. Thanks for the help.

Hello again. I have two fossils I've had labeled as coprolites and just found out they may be something else??? The smaller of the two (1st photos) is 20L x 7W x 15Hmm and was listed as "Turtle Poop" from Salmon Creek, Lewis County, Washington. The second set of photos was listed as "Dino poo from Washington" and is 45L x 20W x 28Hmm with no specific location specified. I'm thinking the 1st item very well may be Turtle Poo, but am unsure of the second item. Looks like it "could be" a Cecum or Cololite. Please let me know what you think. Thanks.
